ASCENDING aorta aneurysms ,COLOR Doppler ultrasonography ,LABORATORY rats ,CALCIUM ions ,HEMATOXYLIN & eosin staining - Abstract
Introduction: Ascending aortic aneurysm is a serious health risk. In order to study ascending aortic aneurysms, elastase and calcium ion treatment for aneurysm formation are mainly used, but their aneurysm formation time is long and the aneurysm formation rate is low. Thus, this study aimed to construct a rat model of ascending aorta aneurysm with a short modeling time and high aneurysm formation rate, which may mimic the pathological processes of human ascending aorta aneurysm. Methods: Cushion needles with different pipe diameters (1.0, 1.2, 1.4, and 1.6 mm) were used to establish a human-like rat model of ascending aortic aneurysm by narrowing the ascending aorta of rats and increasing the force of blood flow on the vessel wall. The vascular diameters were evaluated using color Doppler ultrasonography after 2 weeks. The characteristics of ascending aortic aneurysm in rats were detected by Masson's trichrome staining, Verhoeff's Van Gieson staining, and hematoxylin and eosin staining, while real-time polymerase chain reaction was utilized to assess the total RNA of cytokine interleukin-1β, interleukin 6, transforming growth factor-beta 1, and metalloproteinase 2. Results: Two weeks after surgery, the ultrasound images and the statistical analysis demonstrated that the diameter of the ascending aorta in rats increased more than 1.5 times, similar to that in humans, indicating the success of animal modeling of ascending aortic aneurysm. Moreover, the optimal constriction diameter of the ascending aortic aneurysm model is 1.4 mm by the statistical analysis of the rate of ascending aortic aneurysm and mortality rate in rats with different constriction diameters. Conclusions: The human-like ascending aortic aneurysm model developed in this study can be used for the studies of the pathological processes and mechanisms of ascending aortic aneurysm in a more clinically relevant fashion.

To Study the Correlations of microRNA-155 (miR-155) and microRNA-146a (miR-146a) Expression in Peripheral Blood of Type 2 Diabetes Mellitus (T2DM) Patients with Diabetic Peripheral Neuropathy (DPN), and Explore the Clinical Value of miR-155 and miR-146a in the Diagnosis and Treatment Outcomes of DPN. Methods: The study included 51 T2DM patients without DPN (T2DM group), 49 T2DM patients with DPN (DPN group), and 50 normal controls (NC group). Quantitative real-time PCR was utilized to determine the expression levels of miR-155 and miR-146a. Clinical features and risk factors for DPN were assessed. Multivariate stepwise logistic regression analysis was conducted to confirm whether the expressions of miR-155 and miR-146a could independently predict the risk of DPN. ROC curve analysis evaluated their diagnostic value. Results: The T2DM group exhibited significantly lower expression levels of miR-155 and miR-146a compared to the NC group (P < 0.05). Moreover, the DPN group exhibited a significantly decreased expression level of miR-155 and miR-146a compared to the T2DM group (P < 0.01). Multivariate logistic regression analysis indicated that higher levels of miR-155 and miR-146a might serve as protective factors against DPN development. ROC curve analysis revealed that miR-155 (sensitivity 91.8%, specificity 37.3%, AUC 0.641,) and miR-146a (sensitivity 57.1%, specificity 84.3%, AUC 0.722) possess a strong ability to discriminate between T2DM and DPN. Their combined use further enhanced the diagnostic potential of DPN (sensitivity 83.7%, specificity 60.8%, AUC 0.775). A multi-index combination can improve DPN diagnostic efficiency. Conclusion: The decreased expression of miR-155 and miR-146a in the peripheral blood of T2DM patients is closely related to the occurrence of DPN, highlighting their potential as valuable biomarkers for diagnosing and prognosticating DPN.

Cadmium (Cd) is one of the most toxic and widely distributed heavy metal pollutants, posing a huge threat to crop production, food security, and human health. Corn is an important food source and feed crop. Corn growth is subject to Cd stress; thus, reducing cadmium stress, absorption, and transportation is of great significance for achieving high yields, a high efficiency, and sustainable and safe corn production. The use of silicon or melatonin alone can reduce cadmium accumulation and toxicity in plants, but it is unclear whether the combination of silicon and melatonin can further reduce the damage caused by cadmium. Therefore, pot experiments were conducted to study the effects of melatonin and silicon on maize growth and cadmium accumulation. The results showed that cadmium stress significantly inhibited the growth of maize, disrupted its physiological processes, and led to cadmium accumulation in plants. Compared to the single treatment of silicon or melatonin, the combined application of melatonin and silicon significantly alleviated the inhibition of the growth of maize seedlings caused by cadmium stress. This was demonstrated by the increased plant heights, stem diameters, and characteristic root parameters and the bioaccumulation in maize seedlings. Under cadmium stress, the combined application of silicon and melatonin increased the plant height and stem diameter by 17.03% and 59.33%, respectively, and increased the total leaf area by 43.98%. The promotion of corn growth is related to the reduced oxidative damage under cadmium stress, manifested in decreases in the malondialdehyde content and relative conductivity and increases in antioxidant enzyme superoxide dismutase and guaiacol peroxidase activities, as well as in soluble protein and chlorophyll contents. In addition, cadmium accumulation in different parts of maize seedlings and the health risk index of cadmium were significantly reduced, reaching 48.44% (leaves), 19.15% (roots), and 20.86% (health risk index), respectively. Therefore, melatonin and silicon have a significant synergistic effect in inhibiting cadmium absorption and reducing the adverse effects of cadmium toxicity. [ABSTRACT FROM AUTHOR]

To understand the changes in the peroxiredoxin-2 (PRDX2) expression level in the wound margin tissue (T-PRDX2) of patients with diabetic foot ulcer (DFU) before and after negative pressure wound therapy (NPWT). Additionally, the study aimed to explore the association between PRDX2 expression and the treatment outcome of DFUs to provide a new theoretical basis for revealing the mechanism of NPWT promoting the healing of DFUs. Fifty-six type 2 diabetes patients with foot ulcers undergoing NPWT (the DFU group) and 28 patients with chronic lower limb skin ulcers with normal glucose tolerance undergoing NPWT (the skin ulcer control [SUC] group) were included in the study. T-PRDX2 was detected using Western blotting, and the superoxide dismutase (SOD) activity and the malondialdehyde (MDA) and glutathione (GSH) levels were detected using a biochemical method. In addition, in vitro experiments were conducted to determine the effect of PRDX2 expression on normal human dermal fibroblast (NHDF) proliferation, migration, and apoptosis. Before NPWT, the DFU group exhibited a significantly lower T-PRDX2 expression level compared with the SUC group. After one week of NPWT, the T-PRDX2 expression level, SOD activity, and GSH content in the wound margin tissues of the DFU and SUC groups significantly increased compared with the before NPWT levels. Conversely, the inflammatory indicators (white blood cell, neutrophil percentage, C-reactive protein, and procalcitonin) and MDA content were significantly lower than the before NPWT levels. The expression changes of T-PRDX2 before and after NPWT in the DFU and SUC groups were positively correlated with the 4-week wound healing rate. In vitro experiments demonstrated that PRDX2 could alleviate the oxidative stress in NHDFs, thereby promoting their proliferation and migration, while reducing cell apoptosis. NPWT promotes DFU healing by increasing T-PRDX2, and changes in the T-PRDX2 might be associated with the therapeutic effect of NPWT. [ABSTRACT FROM AUTHOR]

- Abstract
Human CST (CTC1‐STN1‐TEN1) is a ssDNA‐binding complex that interacts with the replisome to aid in stalled fork rescue. We previously found that CST promotes telomere replication to maintain genomic integrity via G‐quadruplex (G4) resolution. However, the detailed mechanism by which CST resolves G4s in vivo and whether additional factors are involved remains unclear. Here, we identify RECQ4 as a novel CST‐interacting partner and show that RECQ4 can unwind G4 structures in vitro using a FRET assay. Moreover, G4s accumulate at the telomere after RECQ4 depletion, resulting in telomere dysfunction, including the formation of MTSs, SFEs, and TIFs, suggesting that RECQ4 is crucial for telomere integrity. Furthermore, CST is also required for RECQ4 telomere or chromatin localization in response to G4 stabilizers. RECQ4 is involved in preserving genomic stability by CST and RECQ4 disruption impairs restart of replication forks stalled by G4s. Overall, our findings highlight the essential roles of CST and RECQ4 in resolving G‐rich regions, where they collaborate to resolve G4‐induced replication deficiencies and maintain genomic homeostasis. Synopsis: CST plays a crucial role in engaging RECQ4 with telomeres, enabling efficient resolution of G4 structures and restarting stalled replication forks. Their cooperative action addresses G4‐induced replication challenges, preserving genomic stability and homeostasis. RECQ4 and CST interact to unwind G4s, thereby resolving replication challenges and maintaining genomic stability.Depletion of RECQ4 leads to G4 accumulation at telomeres, resulting in telomere dysfunction.CST is essential for stabilizing RECQ4 at telomeres, irrespective of telomerase presence.

The subtilisin-like protease (SBT) family is widely known for its role in stress resistance to a number of stressors in different plant species, but is rarely studied in wheat. Subtilisin-like serine proteases (SBTs) are serine proteolytic enzymes that hydrolyze proteins into small peptides, which bind to receptors as signal molecules or ligands and participate in signal transduction. In this study, we identified 255 putative SBT genes from the wheat reference genome and then divided these into seven clades. Subsequently, we performed syntenic relation analysis, exon-intron organization, motif composition, and cis-element analysis. Further, expression analysis based on RNA-seq and tissue-specific expression patterns revealed that TaSBT gene family expression has multiple intrinsic functions during various abiotic and biotic stresses. Analysis of RNA-seq expression assays and further validation through qRT PCR suggested that some of the TaSBT genes have significant changes in expression levels during Pst interaction. TaSBT7, TaSBT26, TaSBT102, and TaSBT193 genes showed increasing expression levels during compatible and non-compatible interactions, while the expression levels of TaSBT111 and TaSBT213 showed a decreasing trend, indicating that these members of the wheat SBT gene family may have a role in wheat's defense against pathogens. In conclusion, these results expand our understanding of the SBT gene family, and provide a valuable reference for future research on the stress resistance function and comprehensive data of wheat SBT members.

Purpose: To study the correlations of miR-222-3p expression in the peripheral blood and wound marginal tissues of type 2 diabetes mellitus (T2DM) patients with the onset of diabetic foot ulcer (DFU), as well as explore the clinical value possessed by miR-222-3p in the diagnosis and treatment outcomes of DFU.Methods: The study included 70 T2DM patients who did not suffer foot ulcers (T2DM group), 146 T2DM patients who suffered foot ulcers (DFU group), as well as 70 normal controls (NC group). Quantitative real-time PCR determined the MiR-222-3p relative expression. Clinical features and risk factors regarding DFU were assessed. Multiple stepwise logistic regression analysis assisted in confirming whether miR-222-3p expression could serve for independently predicting the risk factors for DFU. ROC curve analysis evaluated the diagnostic value exhibited by miR-222-3p level against DFU.Results: T2DM group exhibited an obviously higher MiR-222-3p expression relative to NC group [1.98 (0.98, 3.62) vs 0.92 (0.61, 1.87)] (P < 0.01), but DFU group exhibited an obviously higher miR-222-3p expression relative to T2DM group [5.61 (1.98, 10.24) vs 1.98 (0.98, 3.62)] (P < 0.01). Besides, miR-222-3p expression presented a negative correlation with DFU healing rate (P < 0.05). According to Kaplan–Meier survival curve analysis, the group with high miR-222-3p expression showed higher unhealed DFU cumulative rate relative to the group with low expression (log-rank, P = 0.011, 0.001, respectively). Multivariate logistic regression analysis confirmed that high miR-222-3p expressions could independently predict DFU risk (OR=3.85, 95% CI 1.18~12.37, P = 0.008). According to the ROC curve analysis, the AUC of miR-222-3p specific to DFU diagnosis reached 0.803, with the best sensitivity of 95.93% and best specificity of 96.27%.Conclusion: The increased expression of miR-222-3p in the peripheral blood of T2DM patients is closely related to the occurrence of DFU. MiR-222-3p is a biomarker with potential clinical value in diagnosing and evaluating the prognosis of DFU. [ABSTRACT FROM AUTHOR]

- Abstract
Drug delivery in the brain is challenging due to the existence of the blood brain barrier, which prevents most drugs from entering the target site in the brain. Compared to systematic drug administration, localized and site-specific drug delivery in a minimally invasive manner is effective for the treatment of brain disease. However, its implementation relies on advanced technologies and miniaturized implants/devices for controllable drug delivery. Recent research endeavors have provided a broad range of creative neural implants and platforms for this purpose. In this review, we provide an overview of recent advances in miniaturized neural implants for precise, controllable and minimally invasive drug delivery in the brain. This review will focus on neural implants with proven functionalities by discussing the technologies and materials used to fabricate these miniaturized multi-functional drug delivery implants with either externally connected pumps or integrated microfluidic pumps. The vibrancy of engineering technologies and emerging materials associated with these implants and their significance to targeted and minimally invasive drug delivery for brain disease treatment will motivate continued advance and growth of this area of research.

Platycodonis Radix (PR), a widely consumed herbal food, and its bioactive constituents, platycodins, have therapeutic potential for lung inflammation. Transient Receptor Potential Ankyrin 1 (TRPA1), which is essential for the control of inflammation, may be involved in the development of inflammation in the lungs. The aim of this study was to determine the TRPA1-targeted effects of PR against pulmonary inflammation and to investigate the affinity of PR constituents for TRPA1 and their potential mechanisms of action. Using a C57BL/6J mouse lipopolysaccharides (LPS) intratracheal instillation pneumonia model and advanced analytical techniques (UPLC-Q-TOF-MS/MS, molecular docking, immuno-fluorescence), five platycodins were isolated from PR, and the interaction between these platycodins and hTRPA1 was verified. Additionally, we analyzed the impact of platycodins on LPS-induced TRPA1 expression and calcium influx in BEAS-2B cells. The results indicated that PR treatment significantly reduced the severity of LPS-triggered inflammation in the mouse model. Interestingly, there was a mild increase in the expression of TRPA1 caused by PR in healthy mice. Among five isolated platycodins identified in the PR extract, Platycodin D
3 (PD3 ) showed the highest affinity for hTRPA1. The interaction between platycodins and TRPA1 was verified through molecular docking methods, highlighting the significance of the S5–S6 pore-forming loop in TRPA1 and the unique structural attributes of platycodins. Furthermore, PD3 significantly reduced LPS-induced TRPA1 expression and calcium ion influx in BEAS-2B cells, substantiating its own role as an effective TRPA1 modulator. In conclusion, PR and platycodins, especially PD3 , show promise as potential lung inflammation therapeutics. Further research should explore the precise mechanisms by which platycodins modulate TRPA1 and their broader therapeutic potential. [ABSTRACT FROM AUTHOR]- Published

Head and neck squamous carcinoma (HNSC) induces high cancer-related death worldwide. The biomarker screening on diagnosis and prognosis is of great importance. This research is aimed to explore the specific diagnostic and prognostic biomarkers for HNSC through bioinformatics analysis. The mutation and dysregulation data were acquired from UCSC Xena and TCGA databases. The top ten genes with mutation frequency in HNSC were TP53 (66%), TTN (35%), FAT1 (21%), CDKN2A (20%), MUC16 (17%), CSMD3 (16%), PIK3CA (16%), NOTCH1 (16%), SYNE1 (15%), LRP1B (14%). A total of 1,060 DEGs were identified, with 396 up-regulated and 665 downregulated in HNSC patients. Patients with lower expression of ACTN2 (P = 0.039, HR = 1.3), MYH1 (P = 0.005, HR = 1.5), MYH2 (P = 0.035, HR = 1.3), MYH7 (P = 0.053, HR = 1.3), and NEB (P = 0.0043, HR = 1.5) exhibit longer overall survival time in HNSC patients. The main DEGs were further analyzed by pan-cancer expression and immune cell infiltration analyses. MYH1, MYH2, and MYH7 were dysregulated in the cancers. Compared with HNSC, their expression levels are lower in the other types of cancers. MYH1, MYH2, and MYH7 were expected to be the specific diagnostic and prognostic molecular biomarkers of HNSC. All five DEGs have a significant positive correlation with CD4+T cells and macrophages. [ABSTRACT FROM AUTHOR]

The study of organic semiconductor single crystal (OSSC) arrays has recently attracted considerable interest given their potential applications in flexible displays, smart wearable devices, biochemical sensors, etc. Patterning of OSSCs is the prerequisite for the realization of organic integrated circuits. Patterned OSSCs can not only decrease the crosstalk between adjacent organic field‐effect transistors (OFETs), but also can be conveniently integrated with other device elements which facilitate circuits application. Tremendous efforts have been devoted in the controllable preparation of OSSC arrays, and great progress has been achieved. In this review, the general strategies for patterning OSSCs are summarized, along with the discussion of the advantages and limitations of different patterning methods. Given the identical thickness of monolayer molecular crystals (MMCs) which is beneficial to achieve super uniformity of OSSC arrays and devices, patterning of MMCs is also emphasized. Then, OFET performance is summarized with comparison of the mobility and coefficient of variation based on the OSSC arrays prepared by different methods. Furthermore, advances of OSSC array‐based circuits and flexible devices of different functions are highlighted. Finally, the challenges that need to be tackled in the future are presented.

Flavor is an essential attribute of grapes, but it quickly deteriorates and loses its quality. This study examined the effects of the selenium-chitosan treatment on the amino acid content and volatile components of freshly harvested grapes stored at 0°C. The amount and composition of precursors such as fatty acids and amino acids have an important influence on the formation of aroma compounds. In this article, the amino acids, volatile components, and some enzyme activities of different treated grapes were analyzed. The results of the analysis of free amino acid composition indicated that the selenium-chitosan treatment significantly reduced the loss of amino acid content by inhibiting the activities of glutamate oxaloacetate transaminase (GOT), glutamate pyruvate transaminase (GPT), and pyruvate dehydrogenase (PDH). The analysis also revealed that the significant differences in alcohol and aldehyde compounds primarily accounted for the variation in volatile components between treatments. The selenium-chitosan treatment slowed the decline in the content of aldehyde compounds and inhibited the increase in the range of alcohol compounds. These findings demonstrated that treatment with 25 mg L
-1 selenium mixed with 1.0% chitosan solution has a positive effect on maintaining the flavor of Red Globe grapes. This treatment is worthy of future promotion. [ABSTRACT FROM AUTHOR]- Published

Anion‐coordination‐driven assembly (ACDA) has proven to be a very effective strategy for the construction of polyhedral structures. Here we demonstrate that variation of the "angle" of the backbone of C3‐symmetric tris‐bis(urea) ligands, from triphenylamine to triphenylphosphine oxide, results in the change of the final construct from an A4L4 tetrahedron to a higher‐nuclearity, A6L6 trigonal antiprism (A=anion, herein PO43−; L=ligand). Most interestingly, this assembly features a huge hollow internal space that is divided into three compartments: one central cavity and two large outer pockets. This multi‐cavity character enables the binding of different guests, namely monosaccharides or polyethylene glycol molecules (PEG600, PEG1000 and PEG2000), respectively. The results prove that anion coordination by multiple hydrogen bonds may provide both sufficient strength and flexibility, thus making possible the formation of complicated structures with adaptive guest binding ability.

Radiation-induced intestinal fibrosis, a common complication of long-term survivors after receiving abdominal and pelvic radiotherapy, has no effective clinical drugs at present. Nicotinamide mononucleotide (NMN) has been reported to alleviate a variety of age-related diseases and has potential of regulating gut microbiota. The current study focuses on the role of gut microbiota in chronic radiation induced intestinal fibrosis, and investigates whether NMN plays a protective role in radiation-induced intestinal fibrosis as well as the impact of NMN on radiation-induced dysbiosis of gut microbiota. C57BL/6J mice received 15 Gy abdominal irradiation and NMN (300 mg/kg/day) supplement in drinking water. Feces were collected at 4- and 8-months post-irradiation and performed 16S rRNA sequencing to detect the gut microbiota. Colon tissues were isolated at 12 months after irradiation with or without NMN supplementation for histological analysis. We found that irradiation caused intestinal fibrosis, and altered the β diversity and composition of gut microbiota, while the gut microbiota was observed to be affected by time post-irradiation and age of mice. Long-term NMN supplementation alleviated intestinal fibrosis, and reshaped the composition and function of gut microbiota dysregulated by ionizing radiation (IR). In addition, Akkermansia muciniphila, a promising probiotic, and metabolism-related pathways, such as Biosynthesis of other secondary metabolites and Amino acid metabolism, were more abundant after NMN treatment in irradiated mice. IR has a long-term effect on the gut microbiota and NMN supplementation can alleviate radiation induced intestinal fibrosis by reshaping the composition of gut microbiota and regulating the metabolic function of the microorganism.

However, carbon–carbon (C–C) coupling, the rate-determining step in CO2 R to C2+ conversion, has low efficiency and poor stability, especially in acid conditions. Here we find that, through alloying strategies, neighbouring binary sites enable asymmetric CO binding energies to promote CO2 -to-C2+ electroreduction beyond the scaling-relation-determined activity limits on single-metal surfaces. We fabricate experimentally a series of Zn incorporated Cu catalysts that show increased asymmetric CO* binding and surface CO* coverage for fast C–C coupling and the consequent hydrogenation under electrochemical reduction conditions. Further optimization of the reaction environment at nanointerfaces suppresses hydrogen evolution and improves CO2 utilization under acidic conditions. We achieve, as a result, a high 31 ± 2% single-pass CO2 -to-C2+ yield in a mild-acid pH 4 electrolyte with >80% single-pass CO2 utilization efficiency. In a single CO2 R flow cell electrolyzer, we realize a combined performance of 91 ± 2% C2+ Faradaic efficiency with notable 73 ± 2% ethylene Faradaic efficiency, 31 ± 2% full-cell C2+ energy efficiency, and 24 ± 1% single-pass CO2 conversion at a commercially relevant current density of 150 mA cm−2 over 150 h. CO2 electroreduction to multi-carbon products in acids remains challenging due to the low efficiency and poor stability of C–C coupling. Here, the authors show that asymmetric CO binding at confined nanointerfaces enhances multi-carbon production, improves CO2 utilization, and limits H2 evolution. [ABSTRACT FROM AUTHOR]- Published

Background: At present, there is no clinical study to elucidate the correlation between vitamin D deficiency and the incidence of diabetic foot osteomyelitis (DFO).This study aims to clarify levels of 25-hydroxyvitamin D [25(OH)VD] in peripheral blood and vitamin D receptor (VDR) expression in wound margin tissues (T-VDR) of patients with type 2 diabetes mellitus (T2DM) with diabetic foot ulcer (DFU) and DFO, and to determine its correlation with treatment outcomes of DFU and DFO, and and its value as a potential biomarker for the diagnosis of DFU and DFO. Methods: 156 T2DM patients with DFU (DFU group), 100 T2DM patients without DFU (T2DM group), and 100 healthy controls (NC group). The DFU group patients were subdivided into DFO (n = 80) and NDFO groups (n = 76). The level of serum 25(OH)VD was measured via chemiluminescence immunoassay, and T-VDR expression level was determined by quantitative real-time PCR. Results: The levels of serum 25(OH)VD in the DFU group were significantly lower than the T2DM group [(10.3 (5.8, 18.7) vs 15.7 (8.6, 24.6) ng/mL, P = 0.002)]. Similarly, the levels of serum 25(OH)VD and T-VDR expression in the DFO group were statistically lower than the NDFO group [9.2 (5.2, 20.5) vs 12.8 (6.9, 22.1) ng/mL, P = 0.006)], [1.96 (0.61, 3.97) vs 3.11 (1.36, 5.11), P = 0.004)], respectively. Furthermore, the levels of serum 25(OH)VD and T-VDR expression in DFU patients were positively correlated with the ulcer healing rate of foot ulcer after 8 weeks of treatment (P = 0.031, P = 0.016, respectively). Multivariate logistic regression analysis showed that low level of serum 25(OH)VD was an independent risk factor for DFU and DFO (OR
DFU = 2.42, ORDFO = 3.05, P = 0.008, 0.001, respectively), and decreased T-VDR expression level was an independent risk factor for DFO (OR = 2.83, P = 0.004). Meanwhile, the ROC curve analysis indicated that the AUC of serum 25(OH)VD level for the diagnosis of DFU and DFO was 0.821 (95% CI, 0.754–0.886, P < 0.001) and 0.786 (95%CI, 0.643–0.867, P < 0.001), respectively. When establishing a diagnosis of DFO, the AUC of T-VDR expression level was 0.703 (95%CI: 0.618–0.853, P < 0.001). Conclusions: The levels of serum 25(OH)VD and T-VDR expression in DFU and DFO decreased. Serum 25(OH)VD and T-VDR are potentially valuable biomarkers for diagnosis and prognosis of DFU and DFO..

The aim of our study was to explore circular RNA (circRNA) expression profiles associated with human endometrial carcinoma (EC) and to analyse the molecular mechanisms involved in cancer development and their potential clinical importance. Differential expression profiles were revealed by Arraystar human circRNA microarray analysis. The results of the circRNA microarray were confirmed by quantitative real-time PCR. Interactions between circRNAs and microRNAs (miRNAs) were predicted using Arraystar's miRNA target prediction software. The functions of the circRNA-miRNA coexpression network were identified by KEGG pathway analysis and GO analysis. Compared with para-tumorous tissues, 14 genes were significantly upregulated and 12 genes were significantly downregulated in EC tissues (P < 0.05). The quantitative real-time PCR data demonstrated consistency with the results of the microarray profile analysis. We generated a circRNA-miRNA coexpression network. Hsa_circRNA_079422 expression was significantly lower and miR-136-5p expression was higher in EC tissues than in normal endometrial tissues. KEGG pathway analysis and GO analysis indicated that hsa_circRNA_079422 might play roles in different signalling pathways and biological functions. We confirmed the presence of different circRNA expression profiles and predicted the circRNA-miRNA coexpression network in human EC tissues. Hsa_circRNA_079422 might be involved in the pathogenesis and biological process of EC via interactions with miRNAs. What is already known on this subject? EC is a common malignancy of the female reproductive system. CircRNAs were demonstrated to exert critical roles in cancers, including EC. What do the results of this study add? The results of this study add circRNAs expression profiles, the circRNA-miRNA coexpression network and cancer-related circRNA-miRNA target genes in EC. It was first found that hsa_circRNA_079422 was downregulated, while miR-136-5p was upregulated in EC tissues. What are the implications of these findings for clinical practice and/or further research? In clinical practice, early EC diagnosis lacks specific biomarkers, so most EC patients are diagnosed at an advanced stage. In the management of EC patients, we also lack personalised adjuvant treatment that combines the clinical pathological characteristics. For the existing literature, we identified a new EC differential expression biomarker, hsa_circ_079422. It can be used to verify the correlation with EC clinical severity or poor prognosis. Its targeting can also be used to stratify EC patients with different molecular types, including to guide adjuvant therapy. In addition, we can verify and analyse regulatory pathways associated with it for the design of regulating engineering circRNA. [ABSTRACT FROM AUTHOR]

To investigate the relationship between small noncoding microRNA‐103 (miR‐103) and wound healing of diabetic foot ulcers (DFU) and the underlying molecular mechanism, forty type 2 diabetes mellitus with DFU (DFU group), and 20 patients with a chronic skin ulcer of lower limbs and normal glucose tolerance (SUC group) were included. Quantitative real‐time PCR method was used to determine miR‐103 expression levels in the wound margin tissue of subjects, and to analyse the relationship between the expression of miR‐103 and DFU wound healing. In vitro experiments were also performed to understand the effect of miR‐103 on the high glucose‐induced injury of normal human dermal fibroblasts (NHDFs) cells. The results showed that the miR‐103 expression level in the DFU group was significantly higher than that in the SUC group [5.81 (2.25–9.36) vs 2.08 (1.15–5.72)] (P < 0.05). The expression level of miR‐103 in the wound margin tissue of DFU was negatively correlated with the healing rate of foot ulcers after four weeks (P = 0.037). In vitro experiments revealed that miR‐103 could inhibit the proliferation and migration of NHDF cells and promote the apoptosis of NHDF cells by targeted regulation of regulator of calcineurin 1 (RCAN1) gene expression in a high glucose environment. Down‐regulation of miR‐103 could alleviate high glucose‐induced NHDF cell injury by promoting RCAN1 expression. Therefore, the increased expression of miR‐103 is involved in the functional damage of NHDF cells induced by high‐glucose conditions, which is related to poor wound healing of DFU. These research findings will provide potential targets for the diagnosis and treatment of chronic skin wounds in diabetes. [ABSTRACT FROM AUTHOR]

To investigate the relationship between small non‐coding RNA‐204‐3p (miR‐204‐3p) and the onset and wound healing of diabetic foot ulcers (DFU) and the underlying molecular mechanism, sixty four newly diagnosed patients with T2DM without DFU (T2DM group), 82 T2DM patients with DFU (DFU group), and 60 controls with normal glucose tolerance (NC group) were included. Quantitative real‐time PCR (qRT‐PCR) method was used to determine miR‐204‐3p expression levels in peripheral blood and wound margin tissue of subjects, and to analyse the relationship between the expression of miR‐204‐3p and wound healing. In vitro experiments were also performed to understand the effect of miR‐204‐3p on high glucose induced injury of HaCaT cells (human keratinocytes). The results showed that miR‐204‐3p expression level of peripheral blood in the T2DM group was marked lower than that in the NC group [2.38 (1.31‐5.04) vs 3.27 (1.51‐6.98)] (P <.05). Similarly, the miR‐204‐3p expression level of peripheral blood in the DFU group was significantly lower than the T2DM group [1.15 (0.78‐2.89) vs 2.38 (1.31‐5.04)] (P <.01). The expression level of miR‐204‐3p in peripheral blood and wound margin tissues of DFU patients was positively correlated with the healing rate of foot ulcers after 8 weeks (P <.05). Multifactorial logistic regression analysis showed that decreased expression of miR‐204‐3p in peripheral blood was an independent risk factor for DFU (OR = 2.95, P <.05). The results of in vitro experiments showed that miR‐204‐3p could improve the proliferation and migration of HKC cells and reduce the proportion of apoptosis of HKC cells by targeted regulation of zinc finger protein Kruppel like factor 6 (KLF6) in high glucose environment. Therefore, the decreased expression of miR‐204‐3p in peripheral blood and wound tissue of T2DM patients is closely related to the occurrence and poor wound healing of DFU. The down‐regulated expression of miR‐204‐3p can reduce its ability to antagonise the functional damage of keratinocytes induced by high‐glucose conditions. These results will provide potential targets for the treatment of DFU. [ABSTRACT FROM AUTHOR]

Endothelial cell injury plays a critical part in ischemic acute kidney injury (AKI) and participates in the progression of AKI. Targeting renal endothelial cell therapy may ameliorate vascular injury and further improve the prognosis of ischemic AKI. Here, P‐selectin as a biomarker of ischemic AKI in endothelial cells is identified and P‐selectin binding peptide (PBP)‐engineered extracellular vesicles (PBP‐EVs) with imaging and therapeutic functions are developed. The results show that PBP‐EVs exhibit a selective targeting tendency to injured kidneys, while providing spatiotemporal information for the early diagnosis of AKI by quantifying the expression of P‐selectin in the kidneys by molecular imaging. Meanwhile, PBP‐EVs reveal superior nephroprotective functions in the promotion of renal repair and inhibition of fibrosis by alleviating inflammatory infiltration, improving reparative angiogenesis, and ameliorating maladaptive repair of the renal parenchyma. In conclusion, PBP‐EVs, as an ischemic AKI theranostic system that is designed in this study, provide a spatiotemporal diagnosis in the early stages of AKI to help guide personalized therapy and exhibit superior nephroprotective effects, offering proof‐of‐concept data to design EV‐based theranostic strategies to promote renal recovery and further improve long‐term outcomes following AKI.

KOREAN language - Abstract
With the increase of various media, fonts continue to be newly developed. In Korea, numerous 'Hangul' fonts are also being developed, and as a result, the need for research on determining the similarity between fonts is emerging. For example, when creating a document, the font to be used must be downloaded from each computing environment. However, this is a very cumbersome process. If there is a font that is not supported in the system, the above problem can be easily solved by recommending the most similar font that can replace it. According to this need, we conducted various prior studies for similar font recommendations. As a result, we developed a 'stroke element' that exists in each consonant and vowel in Korean font and developed a font recommendation model using a stroke element. However, there is a limitation in that the existing research was studied only for the structured fonts corresponding to the printed type. Additionally, the font size was not considered in the font recommendation. In this study, two experiments were conducted to expand the font recommendation model by supplementing the limitations of existing studies. First, in order to enable similar font recommendations based on the stroke element even in fonts with various shapes, the font was classified according to the shape, and the stroke elements in each classification were detected. Second, when the font sizes were different, the change in the font recommendations result based on the stroke element was analyzed. In conclusion, we found that it was necessary to find a plan to extract stroke elements for font recommendation of fonts that do not belong to standard fonts. In addition, since the influence of the stroke element varies depending on the size of the font, we propose a stroke element weight model that can be used for recommendation by reflecting it.

Background: Women are at risk of postoperative nausea and vomiting (PONV) after laparoscopic gynaecological surgery. Traditionally, patients who undergo laparoscopic gynaecological surgery are only allowed to initiate oral intake after return of bowel function, including bowel sounds or passage of flatus or stool. The present study was designed to assess the effect of liberal oral intake immediately after discharge from the post‐anaesthesia care unit (PACU) on PONV incidence in patients who underwent elective laparoscopic gynaecological surgery. Methods: In total, 174 patients (aged 20–64 years) were randomly assigned to the traditional and liberal groups. In the traditional group, patients were allowed to initiate oral intake 6 h after discharge from the PACU. In the liberal group, patients were allowed oral intake immediately after discharge from the PACU. The primary outcome was the incidence of PONV 48 h after surgery. Secondary outcomes included ileus incidence, total dose of postoperative opiate (sufentanil) use, time to postoperative first flatus (FFL), first out‐of‐bed mobilisation and the duration of postoperative hospitalisation stay. Results: Incidence of PONV was not significantly different between both groups (32.18% vs. 33.33%, p = 0.872). Time to FFL in the liberal group was significantly shorter than that in the traditional group (14.82 ± 0.91 h vs. 17.50 ± 0.96 h, p = 0.024). The postoperative pain score at 48 h after surgery was significantly lower in the liberal group than that in the traditional group (2.48 ± 0.17 vs. 3.20 ± 0.19, p = 0.008) without an increase in sufentanil use (89.32 ± 1.02 µg vs. 89.92 ± 1.16 µg, p = 0.702). No ileus occurred in either group. When considering the time of actually return to regular diet, initiating regular diet no more than 6 h after discharge from PACU significantly shortened the time to first out‐of‐bed mobilisation (11.18 ± 1.01 h vs. 15.05 ± 0.70 h, p = 0.003). Conclusions: Our results indicate that liberal oral intake after discharge from the PACU in patients aged 20–64 years who underwent gynaecological surgery is safe and beneficial and supports the rationale for a more liberal diet regime postoperatively. Key points: Women are at risk of postoperative nausea and vomiting (PONV) after laparoscopic gynaecological surgery. This single‐centre randomised controlled trial was designed to assess the effect of liberal oral intake immediately after discharge from post‐anaesthesia care unit (PACU) on PONV incidence in patients who underwent elective laparoscopic gynaecological surgery. Liberal oral intake after discharge from the PACU in patients aged 20–64 years who underwent gynaecological surgery is safe and beneficial and supports the rationale for a more liberal diet regime postoperatively.

The co-localization of platelets and tumor cells in hematogenous metastases has long been recognized. Interactions between platelets and circulating tumor cells (CTCs) contribute to tumor cell survival and migration via the vasculature into other tissues. Taking advantage of the interactions between platelets and tumor cells, two schemes, direct and indirect, were proposed to target the modified human serum albumin submicron particles (HSA-MPs) towards tumor cells. HSA-MPs were constructed by the Co-precipitation–Crosslinking–Dissolution (CCD) method. The anti-CD41 antibody or CD62P protein was linked to the HSA-MPs separately via 1-ethyl-3-(-3-dimethyl aminopropyl) carbodiimide hydrochloride (EDC) and N-hydroxysuccinimide (NHS) EDC/NHS chemistry. The size of modified HSA-MPs was measured at approximately 1 µm, and the zeta potential was around −24 mV. Anti-CD41-HSA-MPs adhered to platelets as shown by flowcytometry and confocal laser scanning microscopy. In vitro, we confirmed the adhesion of platelets to tumor lung carcinoma cells A549 under shearing conditions. Higher cellular uptake of anti-CD41-HSA-MPs in A549 cells was found in the presence of activated platelets, suggesting that activated platelets can mediate the uptake of these particles. RNA-seq data in the Cancer Cell Lineage Encyclopedia (CCLE) and The Cancer Genome Atlas (TCGA) database showed the expression of CD62P ligands in different types of cancers. Compared to the non-targeted system, CD62P-HSA-MPs were found to have higher cellular uptake in A549 cells. Our results suggest that the platelet-based and platelet-mimicking modified HSA-MPs could be promising options for tracking metastatic cancer. [ABSTRACT FROM AUTHOR]

Wound closure in fluid‐rich and dynamic environments is challenging. Wound closed by suturing or stapling is prone to tear, causing fluid leakage and inflection. Despite recent advances in tissue adhesive for wound sealing, existing tissue adhesive hydrogels are too soft and stretchable to keep wound edges together under dynamic loading. Here a biodegradable gradient modulus tissue adhesive composite (GmTAC), consisting of three functional components including a tissue adhesive matrix, a gradient modulus micro‐mesh, and an oil‐infused anti‐adhesion surface is presented. The 100 µm thick GmTAC patch can rapidly adhere on wet tissue surface to seal the wound, protect the wound from dynamic tear, prevent adhesion with surrounding tissue, and gradually degrade without the need of patch retrieval. Moreover, an optimally designed GmTAC patch can make the wounded intestine deform like its intact counterpart without visible tear or stress concentration even under large tension or inflation. Efficacy of the GmTAC for wound closure and tear prevention in dynamic and fluid‐rich environments is verified in vitro and in vivo with simulation. This study thereby demonstrates that this strategy has the great potential for the management of challenging wounds. [ABSTRACT FROM AUTHOR]

Purpose: To investigate the correlations of miR-155 expression in the peripheral blood and wound margin tissue of patients with diabetic foot ulcer (DFU) and explore the clinical value of miR-155 as a potential biomarker for the diagnosis and treatment outcomes of DFU. Methods: Sixty newly diagnosed T2DM patients without DFU (T2DM group), 112 T2DM patients with DFU (DFU group), and 60 healthy controls (NC group) were included. MiR-155 levels in the peripheral blood and wound margin tissue were determined by quantitative real-time PCR, while clinical features and risk factors of DFU were explored. Multiple stepwise logistic regression analysis was used to determine whether miR-155 expression was an independent risk factor for DFU. The diagnostic effectiveness of miR-155 level on DFU was evaluated using ROC curve analysis. Results: A significant decrease in the expression level of miR-155 was observed in T2DM group compared with NC group (P < 0.05), while a markedly increased miR-155 expression level was noted in DFU group compared with T2DM group (P < 0.01). Moreover, there was a negative correlation between the expression levels of miR-155 with healing rate of DFU. Kaplan-Meier survival curve analysis showed that the cumulative rate of unhealed DFU in miR-155 high expression group is higher than that in miR-155 low expression group, both in peripheral blood and wound margin tissue (log rank, P = 0.004, P < 0.001, respectively). The multivariate logistic regression analysis confirmed that a high expression of miR-155 was an independent risk factor for DFU. The ROC curve analysis indicated that the AUC of miR-155 for the diagnosis of DFU was 0.794, with the optimum sensitivity being 96.82% and the optimum specificity of 95.93%. Conclusion: The increased expression of miR-155 in peripheral blood of T2DM patients is closely related to the occurrence of DFU. MiR-155 is a potentially valuable biomarker for diagnosis and prognosis of DFU. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Randomised controlled trial showed that dulaglutide can reduce the risk of atherosclerotic cardiovascular disease (ASCVD) in patients with type 2 diabetes mellitus (T2DM), but the underlying mechanisms remain unclear. This study aimed to investigate the effect of dulaglutide on the number and function of endothelial progenitor cells (EPCs) in the peripheral blood of patients with T2DM and its role in improving arterial elasticity, so as to determine potential mechanisms of preventive effect of dulaglutide on ASCVD. Methods: Sixty patients with T2DM were treated with 1000 mg/day of metformin and randomly divided into two groups for 12 weeks: metformin monotherapy group (MET group, n = 30), and metformin combined with dulaglutide group (MET-DUL group, n = 30). Before and after treatment, the number of CD34
+ CD133+ KDR+ EPCs and the brachial–ankle pulse wave velocity (baPWV) of the participants were measured, and EPC proliferation, adhesion, migration, and tubule formation were assessed in vitro. Results: There were no significant differences in the number and function of EPCs and baPWV changes in MET group (P > 0.05). In MET-DUL group, nitric oxide (NO) levels and the number of EPCs increased after treatment (P < 0.05), while the levels of C-reactive protein (CRP), interleukin-6 (IL-6), tumour necrosis factor-α (TNF-α), advanced glycation end products (AGEs), and baPWV decreased (P < 0.05). EPC proliferation, adhesion, migration, and tubule formation abilities were significantly enhanced (P < 0.05). Correlation analysis showed that in MET-DUL group, the changes in CRP, IL-6, TNF-α, and AGEs were negatively correlated with the number of EPCs and their proliferation and migration abilities (P < 0.05). Body weight, NO, CRP, and IL-6 levels were independent factors affecting the number of EPCs (P < 0.05). The changes in number of EPCs, proliferation and migration abilities of EPCs, and NO and IL-6 levels were independent influencing factors of baPWV changes (P < 0.05). Conclusion: Dulaglutide can increase the number and function of EPCs in peripheral blood and improve arterial elasticity in patients with T2DM; it is accompanied by weight loss, inflammation reduction, and high NO levels. Dulaglutide regulation of EPCs may be a mechanism of cardiovascular protection. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Monolayer molecular crystals (MMCs) have attracted worldwide research interest due to their unique properties toward their bulk counterparts. The lower contact resistance of MMCs over their bulk counterparts makes them ideal carriers for studying the intrinsic properties of organic semiconductors. Anisotropic charge transport is an important characteristic of organic single crystals and also one of the primary factors induced in device performance fluctuation; however, related studies based on MMCs are still rare. MMC materials with a weak charge transport anisotropic property would be urgently needed and is of great significance for realizing high performance device arrays with low device-to-device variation. The major difficulty regarding anisotropic charge transport study in MMCs lies in the non-destructive preparation of electrodes on MMCs. Here, by taking advantage of the varied adhesion forces between substrates/gold electrodes/polymer films, the prepatterned fan-shaped electrodes could be readily transferred to target MMCs for the anisotropy study. By this non-destructive dry transferring of top electrodes, anisotropic charge transport properties of typical 2,6-bis(4-hexylphenyl) anthracene (C6-DPA) and 1,4-bis((5′-hexyl-2,2′-bithiophen-5-yl)ethynyl)benzene (HTEB) MMCs were obtained with an anisotropic ratio of 1.15 and 2.15, respectively. The low anisotropic ratio of C6-DPA would facilitate the future applications in MMC OFET arrays without considering the influence of crystal orientation. [ABSTRACT FROM AUTHOR]

- Abstract
Krüppel-like factors (KLFs) are a family of transcription factors characterised by zinc-finger structures at the C-terminal. They play the key roles in cell proliferation, differentiation, and migration, as well as in embryonic development. They have been widely expressed in multiple systems in vivo, and their dysregulation is closely associated with a variety of human diseases. Glycolipid metabolism is a complex physiological process which can be regulated at the transcriptional level. Glycolipid metabolic diseases, such as obesity, non-alcoholic fatty liver disease, diabetes, and their complications, are a serious threat to human health. Recently, increasing studies have shown that KLFs are closely related to glycolipid metabolism and energy balance of the liver, adipose tissue, heart, skeletal muscle, lung, pancreas, and nervous system. In this review, we focused on the correlation between the subtypes of the KLF family and glycolipid metabolic diseases to describe new directions and trends in endocrine and glycolipid metabolic disease treatments.

Aims: Irradiation is an effective treatment for tumors but has been associated with cardiac dysfunction. However, the precise mechanisms remain incompletely elucidated. This study investigated the long-term cardiac damage associated with abdominal irradiation and explored possible mechanisms. Methods and Results: Wild-type C57BL6/J mice were divided into two groups: untreated controls (Con) and treatment group receiving 15 Gy of abdominal gamma irradiation (AIR). Both groups received normal feeding for 12 months. The AIR group showed reductions in left ventricular ejection fraction (LVEF), fractional shortening (FS), left ventricular end-diastolic internal diameter (LVID; d), left ventricular end-diastolic volume (LV Vol. diastolic volume (LV Vol; d) and mitral transtricuspid flow late diastolic filling velocity (MV A). It also showed increased fibrosis, reduced conduction velocity and increased conduction heterogeneity. Non-targeted metabolomics showed the differential metabolites were mainly from amino acid metabolism. Further KEGG pathway annotation and enrichment analysis revealed that abnormalities in arginine and proline metabolism, lysine degradation, d-arginine and d-ornithine metabolism, alanine, aspartate and glutamate metabolism, and arginine biosynthesis. Conclusion: Abdominal irradiation causes long-term damage to the non-irradiated heart, as reflected by electrical and structural remodeling and mechanical dysfunction associated with abnormal amino acid biosynthesis and metabolism.

Anion‐coordination‐driven assembly (ACDA) is showing increasing power in the construction of anionic supramolecular architectures. Herein, by expanding the anion centers from oxoanion (phosphate or sulfate) to organic tris‐carboxylates, an Archimedean solid (truncated tetrahedron) and a highly entangled, double‐walled tetrahedron featuring a ravel topology have been assembled with tris‐bis(urea) ligands. The results demonstrate the promising ability of tris‐carboxylates as new anion coordination centers in constructing novel topologies with increasing complexity and diversity compared to phosphate or sulfate ions on account of the modifiable size and easy functionalization character of these organic anions.

- Abstract
Organic crystals, especially ultra-thin two-dimensional (2D) ones such as monolayer molecular crystals, are fragile and vulnerable to traditional vacuum deposition. Up to now, most of the methods reported for fabricating organic field-effect transistors (OFETs) with top-electrodes on the 2D molecular crystals are based on mechanical-transfer method. Nondestructive method for large scale in-situ electrode deposition is urgent. In this work, the silver mirror reaction (SMR) is introduced to construct top-contact electrodes on 2D organic crystalline thin films. OFETs based on bilayer crystalline films with solution-processed silver electrodes show comparable performance to devices with transferred gold electrodes. In addition to that, OFETs with SMR fabricated silver electrodes show lower contact resistance than the ones with evaporated silver electrodes. Furthermore, the temperature under which SMR electrodes annealed is relatively low (60 °C), making this approach applicable to varies of organic semiconductors, such as spin-coated polymer films, vacuum evaporated films, 2D and even monolayer crystalline films. Besides, OFETs with sub-micrometer channel width and 25 µm channel length are realized which might find practical application in the ultra-small pixel mini/micro-LEDs. [ABSTRACT FROM AUTHOR]

Hemostatic materials are widely used for bleeding control. However, existing blood‐absorbing wound dressing materials have two unaddressed challenges, blood loss through the hydrophilic material and strong clot adhesion that prevents gauze removal. Here, a nonwetting nanofiber structured material based on a two‐step spray coating procedure for hemostatic application is developed. Interfacial behaviors at the blood/clot‐material interface are exploited for bleeding control and minimizing wound adhesion. It is shown that this nonwetting material can retain blood within the wound, thus preventing blood loss. The nanofiber structure and kaolin microparticles collectively promote fast clotting to seal the wound and generate point‐to‐point contacts between clot and the nanofiber surface. These point‐to‐point contacts would subsequently be damaged by the interfacial shear induced by clot contraction, generating a peeling force significantly smaller than commercial low‐adherent or fast‐clotting hemostatic products. Its bleeding control and low adhesion properties are verified by in vivo animal experiments. The work therefore provides an efficient hemostatic material with excellent bleeding control and low wound adhesion properties, demonstrating an effective strategy to design advanced hemostatic materials by exploiting the interfacial behaviors.

Stem cell therapy is widely recognized as a promising strategy for exerting therapeutic effects after injury in degenerative diseases. However, limitations such as low cell retention and survival rates after transplantation exist in clinical applications. In recent years, emerging biomaterials that provide a supportable cellular microenvironment for transplanted cells have optimized the therapeutic efficacy of stem cells in injured tissues or organs. Advances in the engineered microenvironment are revolutionizing our understanding of stem cell-based therapies by co-transplanting with synthetic and tissue-derived biomaterials, which offer a scaffold for stem cells and propose an unprecedented opportunity to further employ significant influences in tissue repair and regeneration.

In this paper, a 3D nitrogen‐doped carbon network with excellent adsorption properties was prepared for bisphenol S (BPS) removal from water. An optimized sample B‐T700‐N3 with high Langmuir specific surface area as well as plentiful heteroatoms was screened out. Benefiting from the synergistic effect of conjugation and hydrogen bonding between the adsorbent and bisphenol S, B‐T700‐N3 demonstrated superior adsorption performance. The maximum adsorption amount (qmax,e) of the B‐T700‐N3 at equilibrium was determined to be up to 91 mg/g, which was comparable or even higher than that of the state‐of‐the‐art reported adsorbents. Experimental results illustrated that this adsorbent could also effectively remove other bisphenols (BPA, BPAF) from water. Overall, this novel adsorbent demonstrated a competitive performance for bisphenols removal in aqueous solution and can be a highly interesting candidate for industrial applications.

A novel gamma aminobutyric acid type B receptor subunit 1a (GABABR1a) biosensor modified with double‐layer gold has been developed for the first time. In this work, the synthesized plasmid was transfected into HEK‐293T cells by liposome transfection, and the target protein GABABR1a was obtained. The horseradish peroxidase was used as a signal amplification system to produce a double‐layer gold modified GABABR1a receptor biosensor. The ligand gamma aminobutyric acid (GABA), jujuboside A and baclofen were detected by the time‐current method with the biosensor. The results showed that the action regularity of GABA, jujuboside A, and baclofen on GABABR1a receptor was fitted with hyperbolic fitting (R2 was 0.9740, 0.9770 and 0.9770, respectively). The double reciprocal method was used to figure out the affinity constant (Ka) of GABA, jujuboside A, and baclofen with the receptor, i. e. 2.1016×10−15 mol/L, 1.7601×10−14 mol/L, and 1.633×10−14 mol/L, respectively, indicating that these measured compounds exhibited different action strength on the receptor. Based on the above, this study will provide a basis for drug screening and will also provide a new idea and method for investigating quantitatively the interaction between receptors and ligands in the future.

Background: lncRNA may be involved in the occurrence, metastasis, and chemical reaction of hepatocellular carcinoma (HCC) through various pathways associated with autophagy. Therefore, it is urgent to reveal more autophagy-related lncRNAs, explore these lncRNAs' clinical significance, and find new targeted treatment strategies. Methods: The corresponding data of HCC patients and autophagy genes were obtained from the TCGA database, and the human autophagy database respectively. Based on the co-expression and Cox regression analysis to construct prognostic prediction signature. Results: Finally, a signature containing seven autophagy-related lncRNAs (PRRT3-AS1, RP11-479G22.8, RP11-73M18.8, LINC01138, CTD-2510F5.4, CTC-297N7.9, RP11-324I22.4) was constructed. Based on the risk score of signature, Overall survival (OS) curves show that the OS of high-risk patients is significantly lower than that of low-risk patients (P = 2.292e−10), and the prognostic prediction accuracy of risk score (AUC = 0.786) is significantly higher than that of ALBI (0.532), child_pugh (0.573), AFP (0.5751), and AJCC_stage (0.631). Moreover, multivariate Cox analysis and Nomogram of risk score are indicated that the 1-year and 3-year survival rates of patients are obviously accuracy by the combined analysis of the risk score, child_pugh, age, M_stage, and Grade (The AUC of 1- and 3-years are 0.87, and 0.855). Remarkably, the 7 autophagy-related lncRNAs may participate in Spliceosome, Cell cycle, RNA transport, DNA replication, and mRNA surveillance pathway and be related to the biological process of RNA splicing and mRNA splicing. Conclusion: In conclusion, the 7 autophagy-related lncRNAs might be promising prognostic and therapeutic targets for HCC. [ABSTRACT FROM AUTHOR]

Cinnamaldehyde (CIN) was added to edible composite films of soy protein isolate (SPI) and egg white (EW) to develop active food packaging. The effects of adding 2%–10% CIN on the structural, physical, and functional properties of the SPI/EW films were systematically evaluated. Fourier‐transform infrared spectroscopy and X‐ray diffraction suggested the excellent compatibility of the components because hydrogen bonding occurred. Scanning electron microscopy indicated CIN affected the structure of the films. The incorporation of CIN significantly improved the antioxidant and antimicrobial activities of the films, but reduced the tensile strength and water vapor permeability. In particular, the addition of CIN at different concentrations significantly increased the elongation at break, water resistant, and UV–vis light barrier properties of the films. Therefore, SPI/EW/CIN films can be used as eco‐friendly bioactive materials in food packaging. Practical applications: In recent decades, many studies were devoted to the development of biodegradable and edible natural biopolymers to replace petroleum‐based polymer packaging. The edible bioactive packaging film can be prepared by adding active substances to the food packaging materials instead of directly adding it to the food, which not only maintains the original characteristics of the food, but also delays the deterioration and autoxidation of the food. This study evaluated the Microstructural, physical, and functional properties (antioxidant and antimicrobial activities) of composite films for use in food packaging and it is proved that it is possible in practical application.

The study aims to explore a new packaging film which is prepared with soybean protein isolate (SPI) and shellac (SHL) and research the effects of the amount of SHL on the water resistance and analyze the cause. Compared with the SPI film, the water resistance including water vapor permeability, moisture content, water absorption, contact angle, the resistance of mechanical strength and appearance to immersion water of SPI/SHL films were significantly improved. The films were characterized by Fourier transform infrared spectroscopy (FTIR), X‐ray diffraction (XRD), and scanning electron microscope. The microstructure of films has been changed by the addition of SHL because the hydrogen bond was formed between SPI and SHL by the results of FTIR and XRD. All results showed that a dense reticular structure was formed with SPI after adding SHL, which improved the water resistance of the composite films. Practical applications: Shellac (SHL), which is recognized as safe by the U.S. Food and Drug Administration, is a natural animal secretory substance with nontoxic, moisture proof, and other properties. Soybean protein isolate (SPI) film is a kind of biodegradable packaging material, which has been studied because of excellent degradability compared with petroleum synthetic polymer. However, the film made from SPI itself is easily soluble in water, which also has the disadvantage of poor water resistance. Therefore, the purpose of this study is to study the effect of SHL on the properties of SPI/SHL composite films and improve the water resistance of SPI film. [ABSTRACT FROM AUTHOR]
